There is no governing body that declares any regulations on what constitutes a skateboard or the parts from which it is assembled. Historically, the skateboard has conformed both to contemporary trends and to the ever-evolving array of stunts performed by riders/users, who require a certain functionality from the board. The board shape depends largely upon its desired function. Longboards are a type of skateboard with a longer wheelbase and larger, softer wheels.
Before learning it, do have your riding basics down. Meaning you are very comfortable riding it around and doing kickturns and not be pushing mongo. Best to learn it whilst stationary with your wheels on a crack so that you don't move and slip out so much. I don't recommend doing it on grass or carpet cos when you pop the tail, it's gonna be absorbed by the floor and when you start doing it on pavement, your muscles will memorize a different way of doing it. So nope, no easy way out i guess.

Longboard - A longboard is similar to a cruiser in terms of overall use and getting around town. Longboards start at about 42 inches in length and about 9 inches in width. When you buy a longboard, the wheel base of the trucks is usually wider and they have wheels starting at roughly 60mm. This gives you more maneuverability and a very smooth ride.

Don’t get your hopes shot if it takes you a while to get this down. Once you know how to ollie, beginner skateboarders you can do any trick in the book with just a little bit of practice. Once you get this trick down while your stationary, go practice while moving around a little bit, try to hop off a couple of curbs. You’ll be skateboarding like a pro in no time. Just keep at it.
After you’ve properly applied a burst of force to the tail, the top-side of your front foot’s toe should start dragging up your board almost automatically. Eventually, the higher you are able to bring your front foot during lift will determine the apex of your ollie, so work gradually towards lifting your front foot as high as your body allows. Skateboarders who record the highest ollies usually (somehow manage to!) bring their feet higher than their hips!
The switch stance ollie uses a similar body motion, but the nollie is subtly distinct: For one, the rider is always moving forward, with the body positioned in a nollie stance--closer to the nose and with the front foot on the nose. Secondly the rider usually postures the body differently so as to compensate for this stance with respect to the forward motion. The rider presses the nose down using their front foot to engage the "pop" motion in order for the board to rise. This is In contrast to a "Fakie Ollie" where the pop motion is performed by the rear foot on the tail, similarly to a normal Ollie, however the rider is traveling backwards when performing a Fakie Ollie. Where in a Nollie the rider is traveling forward with their front foot on the nose to apply the initial force "pop".
4 amazing skateboards in one nice lot. 1. 1990's Tony Hawk Conplete Skateboard, original falcon 3 design. With Rekon trucks and firelite classic wheels. 2. Sk8mafia Lucero deck. Signed by John Lucero. Brand new deck. 3. 1031 deck signed by entire team on a brand new creepy crawl deck. 4. Brand new super rare Big Mess deck with Blast design. This deck is extremely rare and is a must have for any collector. Both the signed decks are personalized to a guy named Jason that owned a skate shop here in Grant's Pass Or. Those guys were on his wall for a long time before he went out of business. If you have any questions or concerns please let me know. Thanks for looking. Steve
